WATER SOFTENER.

Application led July 26, 1926. Serial No. 124,931.

My invention relates to water softeners and particularly to an automatic water softener.

It is the object of my invention to provide an automatic water softener characterized by utilizing a brine tank under pressure from the incoming hard water and further characterized .by having the system controlled by water passing through a control device, such as a meter.

lt is my further object to provide such a system` in which the meterl controls a pair of master valves which are electrically operated7 said master valves in turn controlling the brine water and the flush water application through relatively remote hydrostatic valves which are regulated by the master hydrostatic or needle 'valves controlling the application of hydrostatic power thereto.

Referring to the drawings in detail1 is the inlet hard water line which passes through a screen 2 into the main inlet passageway 3, thence into the meter chamber 4, the details of which will be hereinafter de# scribed, with the result that the meter disk 5 connected to the shaft 6 actuates the pinion 7 which in turn actuates the gear 8, pinion 9, gear 10,*pinion 11, gearb l2 and shaft 13. This shaft 13 carries a driving member 14 which engages with a disk 15. The relative position of the driving member and disk may be regulated by the set screw 16 working in the slot 17 in the shaft 13. This disk is carried by a shaft 2O j ournaled at one end in the housing or casing 18 and further supported by a bracket 19 carried by the casing. Un the other end of the shaft is a worm 21 engaging with a worm wheel 22 carriedA on a cam. `shaft 23 which is supported in a bracket 24..

This cam shaft carries a pair of adjacent contact insulating cam disks 25 and 26 which are made of insulating material of any desired character. Onone side of said disks are the cams 27 and 28.

rThese cams are adjustable relative to the high point of the insulating cam disks by means of set screws 30 and 35 working in slots 31 and 36, said-set screws being carried by the insulating cam disks. The extent of contact of the contacts7 to be hereinafter ldescribed, with these metallic cam disks is determined by the setting of the disks relative to the high point of the insulating cam disk associated therewith.

These two metallic cam disks, known as transmitting disks, have a sleeve 32 connected to them7 such sleeve being projected beyond them providing a surface for a contact roller. This sleeve is supported upon insulating sleeves 33 also mounted on the shaft 23.

The metallic fragmentary contact cam for controlling the application of brine is designated 27 and it is likewise adjustable by a screw 35 carried by the disk 25 working in the slot 36 in the cam 27.

The eXtent of the metallic cam 28 exposed between the end of the high point of the insulating cam at i37 to the en'd of the lhigh point of the metallic cam at 38 determines the period during which the needle valve electrically controlled by the contacts thus made Will remain open for the application of Wash Water or flush water. justment determines the period of application of brine water in connection lwith the end of the high point of the cam 25 at39 with respect'tot'he 'end of the high point of the cam 27 at 40. A space betweenthe ends 'of fthese two high points determines "the period of electrical contact and a secon-d actuation of themas't'er control needle valve controlled thereby. 25 is the nonime'tallic cam. l

The Contact roller arm 41 is -pivoted at 42 on "a bracket 43 Which is mounted onan inslating pla'te The base of the bracket ive-:connected by a terminal rod 45 to a Washer y46 andnut 47 threaded*thereon for engaging `tvitlrari electrical Wire. This rod is "insufla'tetl by an insulating `sleeve 48 passing through the yWall `ot tlie housing 18. This roclenarm 41 is connectedatits lower-'end toalrelical spring 49 which is attached to a lbracket O'nnninted on the i'nsulatiirg plate 44. The Lfur'ictio'n of thisspring ifs to maintain `'this*rol'lei 51 carried on the upper end ot' `the rocle'rarn'r A 41 i-n-A engagement with the sleeve 32. The `Wire 52 connected to the terinirralleads to -a-source of current. A second "rocker -arm i53 is supported on a terminal bracket "54 which is Connected in turn' to'fthe wire 55 Wlrichleads to the solenoid 56. The other end of the solenoid is ennectedjbythe Wi'reiT -to the source of current. The rocker arm 53 carries `acontactrller"58 which VisI adapted to rotateV upon the insulating ca-m 26 and upon occasion upon the high point ofthe contact orftransnitter cam 28. third rocker :arm is carried na terminal bracket-"6() which is connctedbythe vire 61 tothe solenoid 62, the otherl end olf vWhich is connected by a wire. totlrefs'ource o'f current. The rocllzer arm 59"`cairies a; roller" 64 adapted to rotate upon the insti'latingrcam '25 Aand upon the high point of the 'cam A27.

The closing 'ofthe' circuit energizes the solenoid 56 and results in thefmovement of the armature plate 65 Whichcarries Witihit t'liej`va`lvestemr 66 i'vlri'ch has a needleval've headGTclosing the needle valve'aperture 68. This 'needlevalver is normally closed by the helicahspringGQ which surrounds it, such springrcsti-ng its `lowver end upon the plug and its upper end upon a shoulder 71 "on the valve stem 466. Fluid is admitted tothe chamber 72 which pass-es through the passageway 68 into the chamber 73 andthence through thepipe74 'to actuate the desired hydrostatically operated valves.

A similar a dip The fluid for the actuation of such valves enters .the chamber 72 .through `the passage Way 7 5 which leads upwardly from the hard Water line adjacent the meter.

The vfiush water control is identical With the salt control needle valve save 'that one controls the passage of fluid through the ipe Maand the other through the pipe 76.

The pipe 7 4 proceeds upwardly to the hydrostatic:chamber 77 over the diaphragm 78 and the brine control valve 79 actuating the brine control valvestenit() against the resistance "ot" -thespringl which rests ona sup@ porting collar 82 and against a shoulder `83 on the valve'stem. This lmovemeit ofthe valve sten'i'carries with it the valve member, one portion ot-Which 84 seals tl'iebr'ine port 86 land prevents the Ipassage of the brine through the line `867 fth'rough the line 87, thence to the 'top ot theso't'tener 88. 'The lower part of this valve member 89 is adapted' to seal the tpassageway 90 communicating with the line '591 vvhichisa Iflush waterli-ne controlledby the :flush Water valve 92. The line 74=is `coi'mected by the -line 93 tothe drainfpipe 94.

The pipe is lconnectedbyithe pipe95 tothe drain valve 96 which 'is 'normally closed bya spr1`ng,-by the pipe 97 tothe reversing valve 98 which is normally closed by a spring. This line is also connected to the flush Water -valve 92`b'y the p ipe99 and to the bypassvalve `100.

Returning to themeter,it'willl be found that the Water passes into the meter chamber 4 andthroughithe opening 101into the :passagevay f102 through "the passageway i103 down the pipe connected to the lxlittoin of the meter at 104 into fthe bottom of the softener. 'It will be noted that the reversing valve is normally open duri-nig softening.

It isfmaintai-ned open `by the spring 105. The passageway 102 is also connected "to the pipe 196 which leads to the tlushwater valve 92 and the pipe 107 which leadsto'the bottom of1tl1e=brine tank 108. The brine ktank is supplied With a man hole `109 for insert ing vsalt therein.

rFhe'pipe 107f'also communicates with the passageway '110 which is vcontrolled by the drai-nvalve 96, Whiclris normally closed by its spring 112. This controlsthe exlit otfhiid through the drain pipe 94.

Turning to the reversing valve 98,1it will be notedthat it'consists of `a vdiaphragm chamber 113, a diaphragm 114 fand a valve stem 115 carrying a 'diaphragm plate '116 with which the diaphragm engages. The valyf'ey stem also carries a slioulderplate 117 against 'which one end of' the spring 112 engages. The lower end of the spring rests upon the fixed shoulder 1of"anni1`lar, c aracter, designated 118. This shoulder is carriedb'y a sleeve 119 Whichcontains the packing 120 and is threaded intothevalve casing 121at 122. The valve member consists of a plate 123 and a sealing washer 124. This valve 98 is normally open and controlled by hydrostatic pressureto reverse the course of the hard water from the softening tank to the brine tank to force thebrine out of said brine tank and vice versa.

Such a valve asillustrated in Figure 1G is used for the drain valve and for the flush water valve. The valve shown in Figure 14 is similar, save that itis normally open, but is closed by the hydrostatic pressure. Similar numerals indicate similar parts.

The by-pass valve has a construction similar to that shown in Figure 16 save that the valve member 123 is located on top of the partition 125 instead of below it. This partition separates the passageway from the Dipe 126 to the service pipe l127. Introduced into the bottom of the valve 100 is a by-pass pipe 128 which isV provided with a valve seat 129 to receive a valve member 130 which is connected by the valve stein 181 to the service line valve member 123 and so arranged that when the valve member 1 23 is closed, the valve member is at open position. so that the water from the hard water line can flow directly into the service line when the service line is shut off from the water softener during regeneration.

Method of operaza'oa,

tener in the usual manner and out the topv through the pipe 126y past the by-pass valve 100' and into the service line 127, and will continue toy flow so long as the electrical contacts are not made through the agency of the contact cams.

However, when the electrical contacts are made, the solenoids 56 and 62 'are both energized resulting in the opening of the needle valves. which allow hydrostatic pressure from the hardwater line to enter the small pipes and 74 thereby applying the hydrostatic pressure to a plurality of hydrostatic valves. Thus, the flush water control 92 which is effected through pipe 75 conveys pressure over the brine valve opening 85, the valve member 84 allowing the brine which is under pressure from the incoming hard water through the line 107 to be forced through the pipe 86 into the softener 88 at thejtop, down `through the softener. up through the pipe 104, through the passageway V110 past the brine valve 79 which is now open by the pressure in the line 75 to Y. the drain 94. The reversing valve 98 has been closed by the hydrostatic pressure in the line 75 preventing the passage of the brine through the passageway 103 into the passageway 102. The hydrostatic pressure in the line 75 has also opened the flush water valve 92 and has operated the by-pass valve so that no water can flow from the softening system into the service line but hard water can flow from the hard water line through the pipe 128 into the service pipe 127. The valve member 84 carries with it the. valve member 89 sealing the opening or valve seat 90 preventing the passage ofbrine into the line 91. rl`he brine continues to flow so long as the contact is made on the cam 27 between the points 39 and 40. As soon as thisfcontact is broken, the solenoid 62 is deenergized and its spring closes the needle valve shutting off fur-ther soft water because hydrostatic pressure on the salt valve is relieved allowing the valve 84 to Close and open the port 90, but as the pressure is still on the drain valve, the reversing valve and the flush water valve water from the hard water line proceeds up the pipe 106 through the open flush water valvethrough the port 90 to the valve member 89 through the pipe 87 into the top of the softener Y88 out the bottom through the pipe 104 up through the passage way 110 into the drain 94, thus washing out the salt from the softening material so that the salt ywater cannotget into the service system.

During thisl period, the contact roller is on the contact cam 28 between the points 31 and 38. When it drops off of this last mentioned cam 28, the roller then rides upon the insulator. The solenoid 56 is de-energized, the pressure is relieved on the brine valve allowing it to close, the pressure vis relieved on the reversing valve allowing it to open, the passageway of the hard water direct through the passageways 103 and 104 to the bottom of the softener, the pressure is relieved on the flush water valve allowing it to close and the pressure is relieved on the by-pass valve allowing it to close the direct hard water line and open the line from the softener to service.
